If you're so concerned about *data loss* then none of this will be
acceptable to you at all.  We are talking about going from a system
that can actually survive torn-page cases to one that can only tell
you whether you've lost data to such a case.  Arguing about the
probability with which we can detect the loss seems beside the point.
